Anybody have an unusually sweet and personable chicken who wants to brave the danger?

I have 30 chickens and Scump is the sweetest and smartest of the batch, all around more cognizant. She's a certified defender of the bullied and has even stood up to our English bulldog and full sized rooster when she thought they were a danger to the flock(They aren't but she didn't know that). She looks in the places that others don't, she will get into places where all the others can't, and seems to be more observant than even my experienced roosters. Her only downfall is she will forever be cursed in size, have her own places to be, and always at risk of predators if let out to truly free range like the others... that, mixed with her desire to fight off anything that she might perceive as a danger to say... my Jersey Giants... No matter the size of it, just really puts her in a bad spot. Does anyone have any ideas on a solution? I got some chicken diapers and have thought about making her into a house chicken, I work from home so she gets many hours of supervised free range time per day but she will start screaming when I poke my head out of my office and she feels like shes been in the run for too long with some of the others. I avoid poking my head out because her little cries kill me.
